I have three 1967's for you: VIN = 613130 (OHC6) 757 05D = 757th car built the 4th week of May, 1967
VIN = 117594 (400 car) 597th built 03B second week of March, 1967 (Invoiced 3/14/1967 and delivered to CA 3/27/67)
VIN = 139935 665th built 05B second week of May, 1967
The weekly sequencing number is a better indicator of where in line it was built than the VIN. The Vin swings back and forth between V-8 and OHC6 cars while the weekly number remains consistent.
